1 6 Claims. 1

My invention relates to sickle guards and mountings.

One of the objects of my invention is to simplify the sickle guard and its mounting and to eliminate parts where possible.

A further object is to provide a lateral bracing for the guards.

Further objects and advantages of the invention will be apparent from the description and claims.

In the drawings in which an embodiment of my invention is shown, I

Figure 1 is a plan view showing a cutter bar rail and sickle guard mounted thereon;

Fig. 2 is a section on the lin 2-2 of Fig. 1;

Fig. 3 is a perspective view of the sickle guards and mounting, and

Fig. 4 isa section on the line 4-4 of Fig. 2.

Referring to the drawings in detail, the sickle guard and mounting shown comprises a cutter bar rail 1, a plurality of spaced bracket-like tongues 2 secured thereto and extending forwardly therefrom, a wear plate .3 for engaging the rear edge of the sickle bar 4 and supporting it against rearward thrust, a plurality of sickle guard fingers 5, one secured to each of the tongues 2, an apron 6 extendingparallel to the rail I above the tongues 2, a second apron 1 extending parallel to the rail I below the tongues, a plurality of ledger plates 8, one secured to each finger 5 by means of rivets 8 a plurality of holddown clips 9 for holding the sickle sections l against the eldger plates 8, and bolts l l extending through the aprons 6 and 1, clips 9, wear plate 3, guard fingers and tongues 2 for securing them together. The sickle sections III are secured to the sickle bar 4 by means of rivets H Each guard finger 5 comprises an integral metal stamping having an inverted channel portion comprising an upper elongated medial web portion l2 and two elongated spaced flanges I3 extending downwardly from the opposite sides of the upper web portion, respectively. These flanges are spaced far enough apart to enable the insertion and withdrawal of a forming tool by movement transversely with respect-to the medial portion. I

The medial portion l2 comprises a finger tip portion M, a flat ledger plate supporting portion I5 in the rear of the tip portion, a depressed sickle bar clearance portion I6 in the rear of the ledger plate supporting portion, and a flat attaching portion I! in the rear of the clearance portion IS.

The front end of the tongue 2' lies within the channel portion underneath the attaching portion I! and the clearance portion Hi. The side edges of the tongue lie against the flanges l3 to support the guard finger 5 laterally and hold it in alignment. The tongues may be secured to the horizontal flange l8 of the cutter bar rail by' welding. These tongues are doubled over at the front end at IQ for the sake of strength and rigidity.

A pressed sheet metal shield or guard 20 may downward forces acting on the-guard fingers 5.

= The lower apron is secured at its rear edge to any suitable support and serves to resist upward forces acting on the guard fingers. The hold-down clips 9 serve to hold the sickle sections in proper relation with respect to the ledger plates. The shield- 20 may be provided with: an embossment 22 to provide a pocket intowhich the front tip of the ledger plate 8 is inserted to hold it in position and alignment.

Having thus described my invention what I.

claim and desire to secure by Letters Patent is:
